I've never assigned anything via the in-game UI screen. Too wonky and wrecks my .key file formatting. All I've ever used it for is to double-check if a key combo has been assigned already, then I go back to Notepad++ to assign my keys.

Best idea might be to dig into the .key file and manually edit it there. Feel free to PM me or to post the relevant callback lines here if you need any help with that.

Just curious as well.... have you tried Morphine's profile? If you have but are not using it, what's wrong with it in your opinion? IMHO, it is easier to modify a pre-made profile and just change 5-10% of it rather than having to start from scratch and having to do 100% of it.
